'7 Claims.

This invention relates to a flush tank for water closets and improved flush a flush bowl so that has for an object to provide an tank which will cooperate with the flush bowl will project a minimum distance from the wall behind the flush tank.

A further object of this invention is to provide a flush tank having a central recessed portion and two offset wings whereby the recessed portion may cooperate with the flush bowl allowing the flush bowl to occupy a minimum amount of floor space and be placed a minimum distance from the rear wall of the flush tank.

A further object of this invention is to provide an improved means of sealing the flushing bowl to the flush tank have the appearance of whereby the bowl and tank will being a single unitary Figure l is a sectional the constructions, combinations view taken approximately on the line 4--4 of Figure l, and

Figure 5 is a bolts.

The flushing tion consists of a water side elevation of one of the stud bowl I!) constituting this invenbox I! having a pair of forwardly protruding wings l2 and I3 between which is placed a recessed wall M. The recessed wall M has an offset wall l5 through which extends the outlet [8 leading to the inlet ll of the toilet bowl I8. toilet bowl l8 The particular details of this are more particularly set forth and disclosed in a companion case executed of even date herewith by this applicant and filed concurrently herewith.

As will be observed the inlet ll extends beneath the shoulder IQ of the offset |5 and a sealing gasket 20 is provided between the outlet l6 and the inlet 1.

a gasket 22 against The collar 2| is provided 23 through which extends threaded apertures 24 I to receive the studs 25. threaded into these wings through suitable openings in the offset openings in the Within the box I a collar 2| holds the inside of the offset IS. with a pair of wings The studs 25 are 23 and then project l5. These offset [5 are provided with countersunk wells so as to permit nuts 26 to be threaded thereon, holding the collar 2| tight against the gasket 22 and. the inside of the off-- set wall IS.

The toilet bowl I8 is then placed with its inlet l1 against the offset l5 and is provided with suitable apertures to extend over the end of the studs 25. After being put in position with the gasket 20 therebetween, nuts 21 serve to draw the inlet ll of bowl l8 tight against the offset l5 below the shoulder l9, making a very tight seal between the water box I and the toilet bowl I8, and at the same time making the combined water box II and toilet bowl l8 have the appearance of a single unitary construction.

The collar 2| is provided with a flushing aperture 28 leading to the outlet l6, and this aperture 28 terminates in a valve seat 29, against which the soft rubber ball valve 38 is adapted to seat and seal the same. The ball valve 30 is secured on the bell crank 3|, the bell crank 3| being swiveled on a pin 32 extending therethrough and through a pair of lugs 33 on the back of an overflow conduit 34 leading to the aperture 28. This overflow conduit 34 is provided with an overflow pipe 35 for maintaining the water level in box II at the predetermined desired height.

In order to operate the valve 38 and flush the bowl the usual telescoping connecting arms 35 are adapted to be raised by the lever 31 operated 30 by handle 38. A conventional inlet valve 39 is operated by the float 48 in the usual manner and is provided with the usual reseal pipe 4| leading to the overflow 35.

The novel features and the operation of this device will be apparent from the foregoing description. While the device has been shown and the structure described in detail, it is obvious that this is not to be considered limited to the exact form disclosed, and that changes may be made therein within the scope of what is claimed without departing from the spirit of the invention.

Having thus set forth and disclosed the nature of this invention, what is claimed is:

l. A water closet flush tank comprising a water box, a recessed vertical front wall on said water box at the center thereof, a shouldered offset located in said recessed front wall, a discharge outlet in said shouldered offset and a pair of protruding wings on either side of said recessed wall, said discharge outlet in said offset of said recessed wall being adapted to be connected to the toilet bowl, and said protruding wings increasing the capacity of said water box.

2. A flushing tank for water bowls including a vertical front wall, a shouldered oifset in said front wall, a water discharge outlet in said offset, a collar, a valve port through said collar, means for securing and sealing said collar with its valve port leading to the discharge opening through said wall, and a valve seat on said valve port.

3. A flushing tank for water bowls including a vertical front wall, a shouldered offset in said front wall, a Water discharge outlet in said offset, a collar, a valve port through said collar, means for securing and sealing said collar with its valve port leading to the discharge opening through said wall, and a valve seat on said valve port, an overflow conduit projecting from said collar and connecting to said valve port.

4. A flushing tank for water bowls including a front wall, a water discharge outlet in said front wall, a collar, a valve port through said collar, means for securing and sealing said collar with its valve port leading to the discharge opening through said wall, a valve seat on said valve port, and means on said collar above said valve port pivotally supporting a ball valve adapted to close against said valve seat.

5. In a water closet flushing tank having a discharge outlet leading from the tank to the water closet; a valve supporting valve seat member, means for securing said valve seat member in the flushing tank, a valve port leading from said valve seat to the tank outlet, said securing means including a pair of oppositely extending wings threaded stud receiving means in said wings, and threaded studs extending through the flushing tank wall holding said valve seat member in proper position.

6. In a water closet flushing tank having a. discharge outlet leading from the tank to the water closet; a valve supporting valve seat member, means for securing said valve seat member in the flushing tank, a valve port leading from 5 said valve seat to the tank outlet, said securing means including a pair of oppositely extending wings, threaded stud receiving means in said wings, and threaded studs extending through the flushing tank wall holding said valve seat member in proper position, an overflow member projecting upwardly from said valve seat member, and lugs formed on said overflow member pivotally supporting a valve thereon adapted to seat against said valve seat.

7. In combination, a flushing tank and a toilet bowl, means for securing said flushing tank to said flushing bowl, said means including a collar member within said flushing tank, a. gasket member between said collar member and said flushing tank, a second gasket member between said flushing tank and said toilet bowl, stud means threadedly secured in said collar member and extending through said flushing tank and said toilet bowl, nut means on said stud means drawing said collar member against said flushing tank, a second nut means on said same stud means securing said toilet bowl against said flushing tank, an outlet passage extending through said collar member, gasket means, flushing tank, into said toilet bowl, a valve seat on said discharge outlet of said collar member, and means on said collar member pivotally supporting a valve member adapted to close against said valve seat.
